'97 GMC K1500, have only owned since May. It has 180,000 km on it so I didn't expect issues like this.
I started having a problem where the clutch pedal would go soft and I'd lose the clutch intermittently. It would work after pumping the pedal a lot - sometimes over 100 times to get started, and I was pumping constantly at every red light and stop sign. At one point, I was even pumping between gears because 3rd gear synchro isn't good enough to powershift into 3rd.
I took it in. Mechanic said it's either the master or slave cylinder, and being an internal slave let's do the master first. Ok, makes sense to me. He replaced the master and the truck drove perfectly for two weeks, but now it's back to the same problems. Not quite as bad yet, I only have to pump ~30 times before I start driving and a few times per stoplight.
Can a new master cylinder fail that quickly, and if so is there something else causing it?
If it's the slave, why did replacing the master fix the symptoms for two weeks?
Thanks...
